Answer:

The Olympian completed the 100-meter dash 4.75 seconds faster than the gym teacher. You could also say he was 3.25 meters per second faster.

Step-by-step explanation:

To get 4.75 I just subtracted and found the difference between both of their times.

To find the difference between their speeds, I divided 100 by each time to get each person's distance per second. The olympian's speed was 10.05 meters per second and the gym teacher's speed was 6.80 meters per second. To find the difference between these, I subtracted the same way I did with the time difference.
